Asynchronous circuits can provide an elegant and high performance interconnect solution for synchronous system-on-chip (SoC) designs with multiple clock domains. This 'globally asynchronous, locally synchronous' (GALS) approach simplifies global timing and synchronization problems, improving performance, reliability, and development time. Fulcrum Microsystems' SoC interconnect, 'Nexus', includes a 16 port, 36 bit asynchronous crossbar which connects via asynchronous channels to clock domain…

It required only a few man-months of effort to develop a complete gate-level design and physical floor-plan which can run simple C programs such as Dhrystone, and a test chip is expected in 2013.
An Efficient Clocking Scheme for On-Chip Communications
An efficient synchronizer for on-chip communication based on mesochronous clocking scheme that can endure frequency drift between two clock domains and saves around 74% of power consumption is proposed.
An asynchronous NOC architecture providing low latency service and its multi-level design framework
The proposed NOC protocol and its asynchronous implementation are presented as well as the multi-level modeling approach using SystemC language and transaction-level-modeling, which shows that the asynchronous NOC can offer 5 Gbytes/s throughput in a 0.13 /spl mu/m CMOS technology.

The proposed on-chip interface not only handles the resynchronization between the synchronous and asynchronous NoC domains, but also implements NoC communication priorities, and a new concept of mixed synchronous/asynchronous dual mode NoC port is proposed as an efficient off-chip NoC interface for NoC-based open-platform prototyping.
On-chip surfing interconnect
This thesis extends the application of surfing to on-chip interconnects and introduces surfing RC interconnect and surfing LC interconnect techniques and uses distributed varactors to dynamically vary the latency of LC interConnects and thus effect surfing.

Parameterized first-order models for throughput, energy, and bandwidth are presented which allow apples-to-apples comparisons against different design targets and pipeline methodologies and allow designers to understand tradeoffs between implementations that have a varying degree of timing assumptions and design requirements.
Delay insensitive system-on-chip interconnect using 1-of-4 data encoding
A delay-insensitive, asynchronous approach to interconnect over long paths using 1-of-4 encoded channels switched through multiplexers, which shows that it can provide a higher throughput than the simpler tristate bus while using a narrower datapath.
Efficient self-timed interfaces for crossing clock domains
This work presents implementations of STARI where the FIFO consists of a single, handshaking stage, and shows that the STARI interface can exploit the stability of typical clocks to achieve low latencies and negligible probabilities of synchronization failure using very simple hardware.
Pipelined Asynchronous Circuits
A design style for implementing communicating sequential processes (CSP) as quasi delay insensitive asynchronous circuits, based on the compilation method of [1], which can easily implement circuits with some slack between inputs and outputs is presented.
